Question 94 MCQ · 2.0 marks
Consider a Convolutional Neural Network which processes an RGB image. It has 128 kernels each
of spatial dimension 5 × 5 in the first layer. They are convolved with a stride 1. This is followed by a
max-pooling layer with stride 2 and kernel size 5 × 5. What would be the receptive field size of a
single neuron in the pooling layer? (Recap: A receptive field is the size of the region in the input
image, which influences the activation of that specific neuron.)

Question 97 NAT · 2.0 marks
What is the size of the feature map after applying two successive convolution operations with
given parameters? Image size = 64 x 64, Kernel size = 6 x 6, Padding = 1 and Stride = 2. (In
calculation, take floor(x) whenever x is non-integer. If the answer is FxF, write F in the blank).

Question 98 NAT · 2.0 marks
Let an input to a convolutional layer in a CNN have size Df × Df × M where Df = 64 and M = 16, and
output feature map (after passing input through conv layer) has Df × Df × N size where N = 8. Let
the kernel in the conv layer be k × k where k = 3. Calculate the number of parameters for this
convolution layer. (Assume appropriate padding is applied for all convolutions so the input and
output sizes are equal. Ignore the bias term in the calculation).
